WebbValence bond theory suggests that H 2O is sp 3 hybridized in which the 2s atomic orbital and the three 2p orbitals of oxygen are hybridized to form four new hybridized orbitals which then participate in bonding by overlapping with the hydrogen 1s orbitals. As such, the predicted shape and bond angle of sp 3 hybridization is tetrahedral and 109.5°. Bent's rule can be used to explain trends in both molecular structure and reactivity. After determining how the hybridisation of the central atom should affect a particular property, the electronegativity of substituents can be examined to see if Bent's rule holds. Knowing the angles between bonds is a crucial component in determining a m… how do you scan a code with a mobile device
